FORESTS;
A forest, also referred to as a wood or the woods, is an area with a high density of trees. Forests cover approximately over 9.4% of the earth’s surface * USES OF FORESTS;
Forests are important to the survival of human beings mainly because we are dependent on a significant degree of vast areas of forests. The following states the various uses of forests; * Habitat for wildlife.

* Home for plants.
* Flora and fauna.
* Forest plants can be used for medicinal purposes.
* Recreational activities (Camping, fishing, hiking)

* ROLE OF THE FORESTS;
a) Promotes RainfallLarge forests release a significant amount of moisture into the atmosphere through the process of transpiration. As this moisture condenses, gradually precipitation occurs. If all forested areas are removed then rainfall will decrease which could lead to drought. b) Prevents Soil ErosionThe soil is protected by vegetation in various ways;I) The leaves and the branches of trees break the force of rain, therefore reducing the breaking up of soil.II) The roots facilitate rainwater to soak in the soil. So as the water percolates underground there is a decrease in run-off.III) The roots hold the soil tightly preventing it from being washed away. c) Prevents FloodingSince the roots allow the water to penetrate into the soil, it not only reduces run-off but also prevents flooding in low-lying areas. d) Maintains the composition of the atmosphereDuring the process of respiration human beings uses the oxygen content in the in the atmosphere, which means that exhaled air contains a higher percentage of carbon dioxide, thus lowering the amount of oxygen. This imbalance is corrected by the plants during the process of photosynthesis where carbon dioxide is used therefore the oxygen content is normalized. e) Reduces Noise PollutionNoise Pollution is very injurious to health. Noise is produced in variety...
